A fixed frame that is locked to 75 and is located between the fixed frame 48 and the sliding frame 77 located above the sliding frame 77 and below the sliding frame 77.
The space between 48 and the sliding frame 77 is closed.

The fixed frame struts 48 of the fixed frame 62 are inserted into the upper and lower ends of the sliding frame stanchion 63 of the sliding frame 77, and the fixed frames 48 on the upper and lower sides are fixed to the window sash. , Sliding frame
77 slides up and down, and the sliding frame 77 is fixed by screwing a fixing screw 100 provided on the sliding frame column 63.

The window frame 47 constructed as described above is attached to the sash of the window as follows.

First, at the bottom of the window sash, the lower fixing frame
The fixing screw 61 provided on the mounting bracket 57 of 62 is screwed to clamp and fix the lower portion of the sash between the fixing screw 61 and the connecting plate 56. Then, the fixing screw 61 provided on the mounting bracket 57 of the upper fixing frame 62 is screwed, and the upper portion of the sash is sandwiched and fixed between the fixing screw 61 and the connecting plate 56. After that, the height of the sliding frame 77 is adjusted to a height at which the window frame holder 32 of the intake / exhaust duct 30 in which the main body side holder 31 is attached to the main body 1 can be attached to the rotation holder 77.
The fixing screw 100 is screwed to fix the fixed frame 62 and the sliding frame 77.

At this time, depending on the height of the window sash, there may be a case where it cannot be attached to the sash even when the window frame 47 is shortened to the minimum height. In this case, as shown in FIG. 15, one end side where the pair of L-shaped ribs 97, 98 of the one bellows-like closing member 96 is formed is cut to a desired length. The cut portions are locked by the L-shaped ribs 97 and 98 by making the heights of the L-shaped ribs 97 and 98 different from each other.

Next, the operation will be described. The compressor 16 and the first
When the motor 22 and the second motor 27 are driven, the first motor 22
The cross-flow fan 21 is rotated by the driving of the cross-flow fan 21, and the air sucked from the indoor side intake port 5 by the driving of the cross-flow fan 21 is cooled by the cooler 20.
And is exhausted from the indoor side exhaust port 6. The cold air from the indoor exhaust port 6 is blown in a desired direction by the airflow direction left / right changing blade 7 and the wind improving / downward changing blade 8. Also,
By driving the second motor 27, the sirocco fan 26 rotates,
The condenser 25 is cooled by the outside air taken in from the intake duct 33 of the intake / exhaust duct 30 by the rotation of the sirocco fan 26, and is exhausted to the outside through the exhaust duct 34.

At this time, the exhaust air from the exhaust duct 34 becomes warm air by cooling the condenser 25 and moves upward, so that the exhaust air from the intake opening 89 located below the exhaust opening 89 of the window frame 47. Exhaust from the exhaust duct 34 is not sucked from 88.

Since dust and insects are removed from the outside air taken in through the intake duct 33 by the filter 90, dust and insects are prevented from entering the main body 1 through the intake duct 33. Can be prevented. Also, the exhaust duct
Since the filter 34 is also covered with the filter 90, dust, insects and the like will not enter the main body 1 through the exhaust duct 34 even when the operation is stopped. Furthermore, when the filter 90 is used for a long period of time, it is clogged with dust or the like particularly on the intake side, but since the filter 90 is formed rotatably by the mounting screw 91, it can be rotated 180 ° if necessary. ,
That is, the portion of the filter 90 covering the intake duct 33 can be moved to the exhaust duct 34 side, and the exhaust gas from the exhaust duct 34 can be used to clean the filter 90.

The main body 1 may be used at a position away from the window frame 47 due to room layout or the like.
Since the main body 1 is rotated away from the window frame 47, the intake / exhaust duct 30 is not loaded.

[0031]

As described above, according to the present invention, since the hot air exhausted from the exhaust opening is not sucked again from the intake opening, the cooling efficiency of the outdoor heat exchanger can be improved. There is an effect such as being able to.
